What keeps objects from floating out of your hand? What if your feet drifted away from the ground? What stops everything from floating into space? Gravity. As in his previous books, Redwoods, Coral Reefs, and Island, Jason Chin has taken a complex subject and made it brilliantly accessible to young readers in this unusual, innovative, and very beautiful book.

Defines gravity and discusses how our knowledge of the natural force has broadened and evolved.

This book introduces readers to the science behind gravity, explaining the physics behind the phenomenon through graphs and activities. Easy-to-understand summaries following each chapter highlights the most important points for review.

Dr. Cosmic's class of clever monsters experience gravity and weightlessness, a close encounter with an astroid, and what it's like being on the other planets of the solar system, in this blend of adventure and exploration.

"Now a fugitive, Willa leaves Chicago and goes on the run! But when she takes refuge with some low-G farmers, she stumbles into a plot to attack the city. Oh, and on top of all that: giant, man-eating bugs! Maybe we should have led with that."-- Amazon.com.

On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed forever. Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves—ripples in the fabric of space and time—are unrelenting, passing through barriers that stop light dead. At the two 4-kilometre long LIGO observatories in the US,...

What exactly is physical reality? In elegant and accessible prose, theoretical physicist Balungi Francis leads us on a wondrous journey from space time singularities to Quantum Black Holes without information loss, from the Bekenstein-Hawking Area entropy law to his famous Volume entropy law of Black holes, from Modified Newtonian Dynamics, Dark Matter to Planck mass particles, from White Dwarfs to Black Holes and from General Relativity to his own...

This book is an overview of both the history of aliens and UFOS, as well as a review of hidden aerospace and propulsive technologies.Where did these technologies come from? And how have they developed in the intervening years?What are some of the Alien races which exist? Do we have a secret space force and are their secret bases on the moon?Also, I try to answer some questions of how likely some of these claims are-because some things having to do...

"The New Theory of Gravity and Antigravity" is a researched scientific study explaining the concept of gravity and why it exists. Author R.E. Klapka hypothesizes that reversing gravity will cause antigravity, or weightlessness. The book delves into the heart of the atom to find out why mass has a charge and how that charge causes polarization because of Earth's great charge. Our solar system is polarized with negatively charged planets and a positively...

Simple language and humorous illustrations show how forces make things move, prevent them from starting to move, and stop them from moving.
